INVENTOR Eugene fiberkow/fz I I I ATTORNEY Patented Aug. 4, 1936 pairsvsr'rss ossics 8 Claims.

This invention relates to envelopes and particularly to one of the tagtype that is attached to a package or other article to contain anenclosure. such as a Way ticket, bill of lading, memorandum, or thelike, the principal objects of the invention being to provide anenvelope of this character which is of stronger construction towithstand wear and tear incidental to shipping practices, to provide anenvelope construction which better protects its contents from theelements, to provide an envelope which is self-openingupon pressureapplied to the sides thereof when held between the fingers and thumb ofthe hand, and to provide an envelope which is more attractive andfinished in appearance.

In accomplishing these and other objects of the invention, ashereinafter pointed out, .I have provided improved details of structure,the preferred form of which is illustrated the accompanying drawing,wherein: Fig. 1 isa perspective View of the upper portion of a milk canillustrating the attachment of a tag envelope embodying the features ofthe present invention.

. Fig. 2 is a perspectiveview of the'rear side of the envelope, theflaps lacing shown in closed position and a strand extending through theopenings "in the envelope to attach it to an object, such as the canillustrated in Fig. 1.

Referring more in detail to the drawing:

1 designates an envelope constructed in accordancewith the presentinvention and formed from a blank 2 which includes a front portion-3 andflaps i and 5 extending coextensively with the opposite sides of theportion 3 and foldable there over to form the back portion 6 of theenvelope.

The flaps i and 5 have a combined width greater than that of the frontface portion 3 so that overlap a material distance when in foldedposition as shown in Fig. 6 to reinforce the length of 'theenvelope andto provide a seam of extra thickness through which the attaching strandis extended as later described.

Formed on the lower end of the front face portion 3 and extending acrossthe width thereof is a flap i adapted to fold over the lower ends 8 and9 of the flap-s 4 and 5 that form the back of the envelope.

The upper end of the front portion has a closure flap l8 preferablyhaving an arcuate outer edge ll of different radius than thecorresponding edges l2 and E3 of sectional flaps M and I5 that areformed respectively on the upper ends of the flaps l and 5.

The flap 4 and bottom flap 1 are provided with spaced parallel gumstripes l6ll and I8l9 to seal the flaps when the blank is folded as nowto be described. f

The flap 5 is folded over the inner face of the front portion 3, afterwhich the flap '4 is folded over the outer face of the flap and the flap1 is folded over the lower ends 8 and 9 of the flaps 4 and 5 to form anenvelope closure. The adhesive stripes l6-ll and l8l9 are preferablydried under pressure to give what is known as a welded effect, therebyestablishing very rigid and water proof joints which are not subject todeterioration by the elements.

When the envelope is folded as above described, the closure flap H! onthe front portion 3 and the closure flap 28 that is formed by the flapsections M and i5 project outwardly from the planes of the front andback sides of the envelope as illustrated in Fig. 4. The flap it beingof different curvature is preferably of longer length than the flap 26to provide a lip portion 2! which extends over the edge of the flap Itto form a water shed when the flaps are folded as later described.

After theenvelope is folded, as above described, the body portionthereof is provided with an opening 22 extending through the overlappedseam of the back portion of the envelope and an aligning opening 23 inthe front portion 3. The closure flaps l6 and 26 are also provided withopenings 24 and 25 of larger diameter than the openings 22 and 23 in thebody portion, but which have their centers located at substantially thesame distance from the fold line 26 so that when the flaps Ill and arefolded over the back portion of the envelope, the openings 22 and 23will align with theopenings 24 and to permit passage of a strand such asa wire or string 21 by which the envelope is attached to the packagebeing shipped, for example, the milk can, as shown in Fig. 1.

it is, therefore, apparent that due to the arrangement of openingsextending through the relatively wide seam and the double closure flaps,the wire is extended through six thicknesses of material asbest'illustrated in Fig. 5 so that it is not necessary to usereinforcing washers or grurnmets to prevent the wire from pullingthrough the envelope. It is also apparent that due to the lip 2|, theouter closure flap extends beyond the inner flap to enhance the finishedappearance of the envelope and produce the water shed above noted.

In using an envelope constructed as described, the way bill or the likeis inserted through the mouthof the envelope and both closureflaps arefolded back over the back portion of the envelope as shown in Fig. 2. Astring or wire 21 is then passed through the aligning openings to attachthe envelope to the article being shipped.

In the case of the milk can as shown in Fig. 1, the tag may be attachedby the sealing wire which seals the top of the can by passing one end ofthe wire through the openings in the envelope prior to attachment of theseal. The seal, therefore, not only seals the can, but seals the wayticket or other memorandum enclosed in the envelope.

When the envelope is to be opened, the attaching wire is removed and theclosure flaps are unfolded so that they lie in the plane of the frontand back portions of the envelope, whereupon the envelope is retained inthe palm of the hand and gripped between the thumb and fingers thereof.Upon pressure applied to the sides of the envelope, the mouth of theenvelope will be caused to open as shown in Fig. '7 to permit readyremoval or insertion of the contents.

From the foregoing it is apparent that I have provided an envelope whichis not only very convenient to use, but it is of strong construction.and able to withstand exposure to the elements.

What I claim and desire to secure by Letters Patent is:

1. An envelope of the character described including a face portionhaving an opening therein, flaps overlying the face portion and havingoverlapping edges sealed to each other to form a relatively wide seam ofdouble thickness and provided with an opening in registry with the firstnamed opening, and extensions on said overlapped flaps and connected bysaid seam to form a closure flap having an opening therein extendingthrough said seam and adapted to register with said other opening uponfolding of said closure flap to pass an attaching element therethrough.

3. An envelope of the character described including a face portionhaving an opening therein, side flaps overlying the face portion andhaving overlapping edges sealed to each other to form a relatively wideseam of double thickness substantially in the longitudinal center of theenvelope and provided with an opening extending through said seam inregistry with the first named opening, a closure flap on the faceportion having an opening therein adapted to register with said otheropenings, and a flap similar to the closure flap and formed as acontinuation of the side flaps whereby said seam extends across saidflap and provided with an opening registering with said other openingswhen the closure flap and said last-named flap are folded together topass an attaching element therethrough.

4. An envelope formed of sheet material folded to form front and backportions to provide a pocket therebetween for an enclosure, a bottomflap on one end of one of said portions and sealed to the other to closethat end of the pocket, flaps on the opposite ends of said portionsfoldable back over each other and over one of said portions to close theopposite end of the pocket, and

a seam extending longitudinally of one of said 9 portions and extendingthrough one of the lastnamed flaps, said envelope having an openingextending through said last-named flaps and seam whereby a strandpassing through said opening engages six thicknesses of material.

5.
